No natural gas? Have you thought about using efficient liquid propane? Are you looking for comfortable and convenient use of hot water when away from home? Don't worry; propane tankless water heaters are the solution you are looking for.
Tankless heaters powered by propane gas, or liquid propane (LP or LPG) can be used for domestic water and space heating in the same way as natural gas. If you plan to go camping, stay at the cottage or RV-ing, and if natural gas and/or electricity are not available, you can use propane-powered portable heaters.
Combining propane's effectiveness and the convenience of tankless water heaters, these devices will offer fantastic quality and versatility. Come and learn more about them!
Efficiency and excellent performance that's what LP offers over natural gas, but not the only advantage you will get. Propane sometimes makes more sense; it is a lot cleaner for the environment and even easier to use.
When you combine propane and tankless water heaters – the result is even better. Superb performance, convenience, and outstanding results overall – that's what you get with propane tankless water heaters.
Propane heaters are not the most affordable fuel, but could be cheaper than electricity or oil. And combining it with the tankless water heater, which provides greater savings over tank-type (over 30%), you will get better savings throughout the year.
As it offers more power than a heat pump and as it is more efficient than natural gas, a propane heater could offer up to 95% of heating efficiency – making it a great option in some regions. When you add the tankless feature, you can save even more propane and reduce costs exponentially while having a longer lifespan.
As well as producing less carbon dioxide, a propane tankless water heater also reduces the carbon footprint and does not contaminate the environment as bad as others. Being one of the cleanest fossil fuels in the market (more than gas and oil), it will help you heat water more efficiently and without side effects.
Easily stored, transported, and even reliable due to its liquid state, propane is very convenient to use. Capable of heating practically anything, it is also incredibly fast to heat (almost twice as fast) as other fuels and even lasts more due to its efficiency.
Propane tankless water heaters are safe to use.
Typically, devices that use LP need to be hundreds of times more resistant and reliable than others. Why? Because propane can travel faster, so it becomes a little squishier in devices. And thanks to its safer formula, propane is actually non-harmful when ignited, so you get a safe fuel option in every way.
Being stored in larger quantities and providing a superior BTU capacity per cubic quantity, propane is almost twice as useful for heating water. While natural gas offers 1,051 BTU per cubic feet, propane offers up to 2,500, translating to higher efficiency for heating devices.
Natural gas is often a much more cost-effective solution than propane. The price of propane, on the other side, is cheaper than oil or electricity. The propane heaters are also cheaper to repair than different types.
Natural gas, when ignited, produces NOx, which is a greenhouse gas that affects the environment. Propane, however, does not do that despite being a similar fuel. Being more efficient and providing more energy per gallon, propane eventually releases much fewer gasses to the atmosphere while producing more energy.
Now that you learn some about propane, it is time to know a little more about tankless or on-demand heaters and compare them to tank-type models.
Tankless heaters are more effective in using water, as they hold almost no water and dispose of fewer amounts. The tank-less design and quality of construction also allow tankless heaters to produce less environmental damage when disposed of.
Without tanks that produce contaminants such as rust and scales – tankless heaters will provide faster and cleaner water directly to your shower or sink. As there is no standing water, hot water is always fresh.
Don't need to wait for the heater to warm up the water; simply turn up the device and open the tap, and hot water will immediately come your way (depends on the pipe length and recirculation availability). Even after hours of use, the water is still hot. Tankless can deliver an endless supply of hot water to any fixture in your home, even multiple fixtures simultaneously.
Tank heaters occupy too much space in houses. With a tankless heater, you obtain one of the most convenient and space-oriented devices in the market, as they are wall-mounted and as small as a small suitcase.
Without having to save up water and heat it in the meantime, on-demand water heaters use up to 40% less energy than tank heaters. This is translated into less monthly costs and less wasted energy & water.
Almost all tankless heaters not only last longer due to their innovative design, but they also demand less maintenance and have more replaceable parts. This means you have a much more convenient and reliable product.
Now that you know why tankless heaters are so amazing and why propane is so effective, it is time to know why tankless water heaters may provide the best results you can think of. Here's why to use tankless propane water heaters:

Propane tankless water heaters are designed to heat water using one or two heat exchangers. They do not store water.
As the water passes through the heat exchanger, the flame igniter activates while the gas valve opens. The fan starts, and once the right amount of gas and air is established, the gas burner ignites, heating water passing through the heat exchanger. Depending on the outgoing temperature of hot water and demand, the unit adjusts the flame (modulation) to maximize efficiency and performance.
Every modern tankless unit is equipped with an electronic board and a microchip that controls and monitors the operation. There are also sensors, such as the flow sensor, which detects when the tap is open, and there is a call for hot water. Every tankless also includes temperature sensors and safety elements to protect the unit.
Models equipped with the recirculation system deliver hot water faster than those without the pump.
Propane gas is delivered to your home in trucks and is stored in propane tanks. Tanks come in various sizes, from 20-lb, which are typically used for barbeques, to 1000-lb used for homes over 4,500 square feet.
Homes with 2,500 square feet would need a 500-gal tank, which is sufficient to run multiple appliances, including a tankless water heater. You would need a refill every six months with such a size, but it depends on the usage.
According to Rinnai tankless water heaters' manufacturer, the annual operating costs of high-efficiency propane tankless water heaters (EF is 0.81) is approximately $552, while for natural gas models is $228. Homeowners of the ultra-high efficiency propane models (EF is 0.92) would spend around $487 per year, while for natural gas type, around $201. The above data is from 2017.
Every gas-operated water heater, including propane tankless, has to be vented. Since there are two types, indoor and outdoor, indoor models must remove the products of combustion to the outside atmosphere, often using power or power direct venting system, while the outdoor models are ventless – they do not utilize a venting system.
With the approved gas conversion kits, some propane tankless water heaters can be converted from propane gas to natural gas and vice versa. The conversion kits must be used and installed by a qualified installer. Gas conversion is not complicated nor time-consuming.
There are only a few tools needed, such as a screwdriver, manometer, and a gas leak detector. An installer will have to install new gas manifold nozzles and a gasket, setting the DIP switch on the PCB to the correct position, check and adjust the gas supply pressure according to the manufacturer's instructions.
There's no other device as efficient and convenient as tankless propane water heaters are. It is easy to install, much easier to use and needs less maintenance than other hot water heaters – getting one of these is a splendid idea. However, choosing one is not that easy.
